Yes, there is a prominent kissing scene in the 2007 Pixar film Ratatouille. It occurs between the main human characters, Alfredo Linguini and Colette Tatou. The scene takes place outside the restaurant while Colette is training Linguini; after a brief, tense argument where she is about to ride away on her motorcycle, Linguini (under the control of Remy the rat) kisses her to stop her from leaving. This moment is a turning point in their romantic relationship and is also notable for a humorous background detail: earlier in the movie, Remy sees a couple in an apartment window having a dramatic fight that ends in a passionate kiss, which inspires him to make Linguini do the same. While the film is rated G, some parents and critics have joked about the "romantic tension" in the movie, but the kiss itself remains the primary display of affection between the two leads. It's a classic example of Pixar's ability to blend slapstick physical comedy with genuine emotional beats.
